2. 1. Resource Conservative Manufacturing : New Generation of Manufacturing

   Author : Farazee Mohammad Abdullah Asif; Mihai Nicolescu; Carmine Bianchi; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Resource Conservative Manufacturing; Multiple Lifecycle; System Dynamics;

   Abstract : The question of resource scarcity and emerging pressure of environmentallegislations have put the manufacturing industry with a new challenge. On theone side, there is a huge population that demands a large quantity ofcommodities, on the other side, these demands have to be met by minimumresources and with permissible pollution that the earth’s ecosystem can handle.

5. 3. A Computational Framework for Control of Machining System Capability : From Formulation to Implementation

   Author : Andreas Archenti; Cornel Mihai Nicolescu; Mamoru Mitsuishi; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machining system; Stability; Statistical Dynamics; Elastic Linked System ELS ; Operational Dynamic Parameters ODP ; Loaded Double Ball Bar LDBB ; Virtual Machining System Engine VMSE ; Contactless Excitation and Response System CERS .; SRA - Production; SRA - Produktion;

   Abstract : Comprehensive knowledge and information about the static and dynamic behaviour of machine tools, cutting processes and their interaction is essential for machining system design, simulation, control and robust operation in safe conditions. The very complex system of a machine tool, fixture and cutting tools during the machining of a part is almost impossible to model analytically with sufficient accuracy. READ MORE

6. 4. Model-Based Investigation of Machining Systems Characteristics : Static and Dynamic Stability Analysis

   Author : Andreas Archenti; Mihai Nicolescu; Amir Rashid; KTH; []
   Keywords : Machining systems; modelling; TECHNOLOGY; TEKNIKVETENSKAP;

   Abstract : The increasing demands for precision and efficiency in machining call for new control strategies for machining systems based on the identification of static and dynamic characteristics under operational conditions. By considering the machining system as a closed-loop system consisting of a machine tool structure and a machining process, the join system characteristics can be analyzed. READ MORE

7. 5. Characterization of factors interacting in CGI machining : machinability - material microstructure - material physical properties
